A small area in Michigan's Upper Peninsula has become a popular attraction for visitors due to a mysterious white light that has been spotted there for decades.
According to a recent report by the Detroit Free Press, the phenomenon, named the Paulding Light after the town, was first noted by authorities in 1966 after a reported sighting.

The light has since taken on a supernatural backstory, with some attributing the bright spot to a railroad worker who died on the job while others think it represents the spirit of a grandparent looking for a grandchild.
In 2010, a team led by Jeremy Bos, a PhD candidate at Michigan Technological University, examined the light from a scientific perspective.
Based on real-world testing and modeling exercises, they determined that the spectacle is likely created by cars traveling on the adjacent highway US-45.
They were also able to explain variations that have been observed; for example, multiple colors are likely projected when a police car pulls a vehicle over.
